Key technology

1. Waste sand filter recycling
Process technology and environmental aspects
: Achievement of low on-site costs through continuous operation Strengthen company reputation by environmental excellence 

Recycling process of waste filter sand 


Result : Ecomomic effect 
▪ Reduction of waste treatment costs
▪ Reduction of new filter sand purchase costs : Recycled filter media 90% + New filter sand 10%
▪ Reducted waste transport costs






2. Cooling tower filter crushing & sorting, recycling
Concept 
: Crushing and recycling technology of generated cooling tower waste filler during filler replacement 

Effect 
▪ Reduce transportation cost through volume reduction up to 10% of existing volume 
▪ Recycling resource 
▪ Reduce waste treatment cost Process

3. Dry ice cleaning by CO2 recycling
Concept 


Comparison sheet between the existing cleaning and dry ice cleaning


Effect 
▪ No pollutant treatment cost 
▪ No damage to basic material 
▪ Short cleaning time 
▪ Non-operation break-up time for facility cleaning 
▪ Possibility of cleaning in small space 
▪ Outstanding sterilization effect 


4. Cardox system (CO2 blasting tube operation)
Concept 
: Technology from Cardox International Ltd., United of Kingdom Cardox system provides the ultimate solution for clearing build-up and blockages in silos, bins, hoppers and most storage vessels. 

Principle 
When energized by the application of small electrical charge, the chemical heater instantly converts the liquid carbon dioxide to a gas. This conversion expands the CO2 – now 600 times the original volume – through a special discharge nozzle to create a powerful heaving force, at pressures up to 40,000psi (3,000bar). This all takes place in milliseconds.

5. SCR(Selective Catalytic Reduction) regeneration, recycling
Concept 
: Ammonia(NH₃) gas is used as a catalyst reducing agent. NOx is selectively reduced without being interrupted by O₂in emissions gas. As a result, NOx is turned into nitrogen and water, finally removed.

Technology characteristics 
▪ Cleaning Process 
On-site mobile regeneration technology
Minimized changes in SCR catalyst physical, chemical, and mechanical properties
and maximize catalytic activity potential 
▪ Impregnation/ Drying Process 
Maintain initial activity level/ improve activity by increasing catalyst coating efficiency and preventing vanadium loss
Maximize catalyst structural stability maintenance and prevent abnormal increase of catalytic inactivation speed
(In-organic binder for coating, vanadium Nano-coating equipment
▪ Condition-based Maintenance 
Catalyst regeneration equipment, regeneration process, and regeneration method standardization
Increased catalyst lifespan through appropriate maintenance cycle according to facility operating hours

6. Bio-degradable cleaner for mineral oils, G-Cleaner
Concept 
: To improve an economic cleaner which provides powerful de-greasing, cleaning, and rust-proofing effects. Also, our process is not required of separate wastewater purification treatment after cleaning 

Metal cleaning & De-greasing principle 


G-Cleaner characteristic 
▪ Eco-friendly
▪ Human-harmless
▪ Plant-based fatty acid colloid cleaning agent (Brownian motion)
▪ Hydrophilic and oil-based molecular property
▪ Nonionic surfactant generating no static electricity
▪ Powerful sterilizing and disintegrating effect 

Result



7. Oil tank sludge discharge : ARC System
Concept 
: To clean and recycle oil sludge and industrial sludge at industrial tanks including crude oil tank

Process

•Setting : Equipment assembling
•Step 1 : Solid oil sludge discharge
•Step 2 : Liquid oil sludge discharge
•Step 3 : Inspection and reporting

Main equipment 


 
8. Crude oil treatment system
Concept
: Pretreatment system means the removal of sludge, water,
especially NORM(Naturally Occurring Radioactive Materials) that cause problem
in maintenance before storage. This system is applied to oil and gas field.
